IP04 vs IP69K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP69K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 6) and liquid protection (level 4 vs 9K). IP04 is rated for no protection and splashing water (all directions), while IP69K provides dust-tight and high-pressure, high-temp water jets.
The IP04 rating offers no protection against solid objects and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 4.
IP69K is dust-tight and resists high-pressure (8–10 MPa), high-temperature (80 °C) water jets. The highest IP rating, required for food, beverage, and pharmaceutical washdown environments.

The exact difference (IP04 vs IP69K)
Solid protection
IP04
Level 0 — No Protection
IP69K
Level 6 — Dust-Tight
IP04 provides "No Protection" (level 0), while IP69K provides "Dust-Tight" (level 6). IP69K is 6 levels higher.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP69K
Level 9 — High-Pressure, High-Temp Water Jets
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP69K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP69K provides 5 levels more liquid protection.

Recommendation
IP69K offers higher overall protection than IP04. Choose IP69K for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
